<p>A disk refiner for refining fiber material. The refiner comprises two opposed refining disks (3, 4), at least one of which is rotary and supported on a rotary shaft (5). The shaft (5) is mounted in a stand (1) via a bearing housing (6) with at least two bearings (11, 12, 13), a first one (11) for axial and prevailing radial forces, and a second one (12) primarily for radial forces. The bearings (11, 12, 13) are mounted rigidly each in its bearing seat (21, 22, 23), which is axially movable in the bearing housing (6), which in its turn is mounted stationary in the stand (1). Between the bearing seats (21, 22, 23) prestressing members (25, 26, 27) are arranged.</p> |
